A friend of mine sent me a video of their Whirlpool direct drive washer, model number WTW5200V02, making a loud hum in the Delicates cycle (and only that cycle) that starts off very loud and then gradually diminishes as the basket gets up to speed. I haven't been out there yet to see it but here's the video he sent me.

What thinkest thou? Bad motor winding for the delicates speed? Anything else that could possibly cause this kind of noise? He lives way over in Vermont so when I go out, I want to have the universe of bad parts with me so I can get it fixed in one trip.

a few notes:
I may be wrong,
That model uses a (1) speed Motor
Replacement is a (2) speed Motor, but only (1) speed is wired.
Delicate uses an "intermittent" Agitate.
Timer Chart shows HI Motor #5 and LO Motor #6, but 5&6 are tied together ..
Timer Chart # 48 is also tied to 5&6
# 13 and # 13A can also power the Motor..

In delicate cycle, the first spin after wash is through timer contact 48 and final spin after rinse is through contact 6. Same as perm press cycle. Could be worn cam in timer. Timer contacts 13 and 13A are not for powering the motor, they are for powering water valves for spray during spin/spray.
